This 18th-century Baroque palace is a beautiful reflection of the battles between the older relatives of Adán de Yarza. It is located in the Leagi district; it is a cubic building erected on a right-angled plan, in which the front part and the edges are treated with ashlar masonry.

Between the two windows and above the main door is the coat of arms of the Leagi family: a helmet decorated with feathers and acanthus leaves and, at the bottom, two children or two angels. The upper part of the coat of arms is divided into quarters, with a wild boar on the first and fourth quarters, and an eight-pointed star on the second and third quarters.
